Cervical Zygapophyseal Joint Pain Patterns I: A Study in Normal VolunteersMB, ANTHONY DWYER, BS, FRACS*; APRILL, CHARLES, MD†; BOGDUK, NIKOLAI‡Spine: June 1990 - Volume 15 - Issue 6 - p 453–457 EUROPEAN EDITION: PDF Only Buy Abstract Author InformationAuthors The pain patterns evoked by stimulation of normal cervical zygapophyseal joints were determined in five volunteers. Under fluoroscopic control, joints at segments C2–3 to C6–7 were stimulated by distending the joint capsule with injections of contrast medium. Each joint produced a clinically distinguishable, characteristic pattern of pain, which enabled the construction of pain charts that putatively could be of value in determining the segmental location of symptomatic joints in patients presenting with cervical zygapophyseal pain. *Department of Orthopaedic Surgery, University of Colorado Health Sciences Center, Denver, Colorado †Diagnostic Imaging, New Orleans, Louisiana ‡Faculty of Medicine, University of Newcastle, New South Wales, Australia. © Lippincott-Raven Publishers.
